AG RICULTU RAL-IMPLEM ENT TOOTH.

SPECIFICATION forming part of Letters Patent No. 677,478, dated July 2,.1901. Application filed February 21, 1901- Serial N|418J3311 (Nomodel.)

To all whom it may concern.-

Be it known that I, HENRY G. SMITH, acitizen of the United States,residing at Ithaca, in the county of Tompkins and State of New York,have invented a new and useful Improvement in Agricultural-ImplementTeeth, of which the following is a specification.

My invention relates to improvements in agricultural implement teeth andthe mechanical device for attaching the same; and the objects of myimprovement are, first, that the double-end reversible tooth-pointhereinafter described maybe more firmly and substantially attached, and,second, that by the use of my device said tooth-point may be attachedwith greater facility, and in so doing the person so attaching may berelieved from the necessity of using a wrench, nuts, bolts, or othercomplicated device. I attain these objects by the mechanism illustratedin the accompanying drawings, in which Figure 1 is a side view of aharrow or other agriculturalimplement tooth complete, together with thedouble-end reversible toothpoint attached with my device, hereinafterdescribed. Fig. 2 shows a rear view of the same. Fig. 3 shows a sideview of-the doubleend reversible tooth-point detached. Fig. 4 shows arear view of the double-end reversible tooth-point detached. Fig. 5shows three different views of my wedge-shaped cotter or key with whichthe said double-end reversible tooth-point is attached to the barrow orother agricultural-implement tooth.

Similar letters refer to similar parts throughout the several views.

In Fig. 1, 0. shows the wedge-shaped cotter or key, which consists of aright-angle-shaped piece of metal or other material driven into positionlongitudinally from above and parallel with both the double-endreversible point and the permanent tooth.

In Fig. 4, showing double-end reversible tooth-point, Z) and I)represent flanges or integral side wings turned back from its centralposition. The wings or flanges may be of equal or unequal width, so thatthey may be readily hooked over and clasped to the permanent tooth. Itis obvious also that the double-end reversible tooth-point must beslightly wider than the permanent tooth from the in- In Fig. 5, showingdifferent views of the cotter or key, 0 represents a section view ofsaid cotter or key. 6 represents said cotter or key as viewed diagonallyfrom the open side thereof. cl represents said cotter or key as viewedfrom the closed side thereof. (1 and 6 represent a projecting lip orhead of said cotter or key, by which the said cotter or key may beeasily driven from its position when attached to the permanent tooth anddouble-end reversible tooth-point.

I am aware that prior to my invention re versible double-endtooth-points for harrows and other agricultural implements have beenused. I therefore do not claim such a com bination broadly; but

\Vhat I do claim as my invention, and desire to secure by LettersPatent, is

1. The combination with the permanent tooth of a harrow or, likeimplement, of the double-end reversible tooth-point described consistingof a plate with integral side wings turned back from its centralposition the inside of said wings being of greater width than thepermanent tooth and the wedge-shaped key shown and described inserted sothat the same will lie over'the edge and side of the permanent tooth andforce the same into position substantially as shown and described.

2. The combination with the permanent tooth of a harrow or likeimplement of the do uble-end reversible tooth-point, aright-angular-shaped key having projecting head and parallel with boththe double-end reversible tooth-point and the permanent tooth anddirectly engaging the same substantially as shown and described.
